Millsy,
You might not need to be so specific with these coils - the KKN336 has a resistance of 85ohms or something.
The KKN332 will be similar.
What happens a lot with old EM's is to get them running etc correct coil may not have been available - hence the inline series resistors you find in these old games - changes your coil value.
Below is a pic of some old bally stuff - the resistance on the coils is 5ohms but you can put an inline resistor in there to approx 70ohms or a potentiometer and adjust to correct setting.
The credit wheel is in the pic also, but if you want some of this stuff, let me know and ill package it up for you
